My Courses
The basic concepts and techniques used in satellite communications are introduced. The three major segments of a satellite system: the space segment, the earth segment and the link between these segments are explained in details. An introduction to satellite launching is followed by a detailed discussion of different orbits and methods of allocating geostationary orbit to communication satellites are addressed. Three main frequency bands allocated to communication satellites are discussed in details. The atmospheric and free space loss, the effects of rain attenuation, elevation angle, antenna’s figure of merit and other factors affecting signal propagation are explained. Uplink and downlink transmissions and the link budgets are examined and the carrier to noise ratio, bit energy to noise density ratio and gain to noise temperature ratio are explained. Different modulation and multiple access methods are covered. The laboratory part of this course utilizes several software simulation tools to analyze the different segments of a satellite communication network. The link budget analysis, launching phase maneuvers and impacts of different parameters affecting signal transmission and reception are performed to improve understanding of the theoretical concepts learned in the lecture part of the course. The impacts of other Earth and Atmospheric parameters such as sand storm, rain attenuation, Van Allen Belts and Tropospheric Scintillation on signal propagation are examined to enhance learning.

A Cybersecurity Awareness Game for Schools
Cybersecurity awareness refers to the comprehension and insight into potential risks to information security. In our modern, interconnected society, every internet user can potentially fall victim to cyber threats such as hacking, phishing, malware, identity theft, and online fraud. Cultivating cybersecurity awareness entails recognizing these dangers and understanding how to safeguard oneself against them.It also involves staying updated with the latest trends in cybercrime and adapting to new forms of online threats that continuously evolve. Educating individuals about cybersecurity encourages them to be careful and watchful while browsing the web. It encompasses the awareness that everyday online actions can expose personal and sensitive information if adequate security practices are not adhered to. For students who invest considerable time online for studying, social interaction, and gaming, cybersecurity awareness is not merely a technical ability; it is an essential life skill. Developing these skills early helps students build a foundation for lifelong online safety, preparing them for both academic and professional digital environments. An essential element of cybersecurity awareness involves instructing students on how to safeguard personal details, create strong passwords, and detect suspicious behaviors. Young users need to be able to identify when a website or email appears untrustworthy, when a stranger reaches out on social media could indicate potential risk, or when sharing excessive personal information could lead to privacy violations. Equally vital is fostering in them the practice of questioning online interactions and seeking guidance from adults when something seems off. In the end, cybersecurity awareness is about equipping students with the knowledge and assurance to explore the internet safely and responsibly. By educating students at an early stage, we enable them to become critical thinkers and responsible digital citizens who can defend themselves and help create a more secure online environment.A strong cybersecurity foundation will not only protect individual students but will also contribute to a broader, safer digital community for everyone. Encouraging collaboration, peer support, and continuous learning ensures that cybersecurity awareness remains a living, evolving skill throughout their lives.
